Trivia Tester : Power Play

Aside from ultralights or any “sport class” aircraft, under what circumstances is it possible for a pilot without a medical to legally fly as PIC in a regular powered fixed-wing aircraft?

Trivia Tester : High, Hot, and Humid

Accidents involving degraded performance due to density altitude continue to plague pilots. The precise effects of temperature upon pressure altitude and related corrections are applied by all pilots, but the one additional ingredient in the mix that affects density altitude, namely humidity, is largely ignored.  What are the approximate respective altitude corrections, in feet, for humid air at 100% relative humidity when the air temperature is 50 °F, 70 °F, 90 °F, and 100 °F ?

Trivia Teasers

1) How long have directions been expressed in degrees clockwise from North?
2) How fast would you need to go in order for at least part of your Skyhawk to exceed Mach One?
3) When may a pilot descend below the glide slope on a visual (or even an instrument approach) and land on the displaced threshold?

Trivia Teasers

1) Airplane propellers generate most of the noise that is the source of complaints (at least those against piston and turboprop airplanes). The noise becomes much worse as propellers reach transonic speeds. If airplane wings can spoof critical Mach numbers by means of their sweep-back, why aren't the propellers on small airplanes also swept back?

2) Based upon the FAA's own data, which do you suppose have been the hardest FAA written tests? Aircraft Dispatcher, Ground Instructor, ATP Helicopter, Flight Instructor Gyroplane, Inspection Authorization.

3) Wherever the President visits, a large chunk of instant Special Use Airspace follows. In this case, 'large' means a cylinder with a radius of up to thirty miles (although at Camp David, it is 'only' 10), and going up to 17,999 feet MSL. What, if any, is the protective airspace around the Vice President?
